Koressia

Koressia was an ancient Greek city-state located on the northwestern coast of Keos. It was located close to Attica on the northwest side of the island, and it could be reached from Athens in 24 hours. Its economy was tied to its silver mines and miltos (used to paint triremes), and, during the 5th century BC, Xenia's fleet of pirates conquered the city from Sparta. In 431 BC, the pirates burned the city to the ground and had every resident over the age of 60 commit suicide with hemlock poison to offset the effects of a food shortage, and pirates patrolled the streets of the lawless city.
